Improved snap-hook



UNITED STATES PATENT OFFICE.

EDWARD A. COOPER, OF BUFFALO, NEW YORK, ASSIGNOR 'IO HIMSELF AND J. M. JOHNSTON, OF SAME PLACE.

iMPRovED SNAP-HOOK.

To all whom it may concern:

Beit known that I, EDWARD A. GooPER, of the city of Buffalo, county of Erie, and State of Neu7 York, have invented new and usef'ul Improvements in Hat-Iless-Snaps5end I do hereby declare that the following is at'ull and exact description thereof, reference being had to the accompanying drawings, and to the letters ofrreference marked thereon, in whichl Figure l is a perspective View of my improved snap. Fig. 2 is a longitudinal section of the same. Fig. 3 is the spring. Fig. 41's the spring With a lip.

rlhe nature and object of my invention is to provide a snap for harness which is sut'e and simple in its construction and cheap in its manufacture.

My invention relates more particularly to the peculiar and novel manner by which I secure the spring which holds the thumb-lever in its place. y

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, Fig. l, represents, in perspective, my improved harness-snap.

B represents the loop by which the snap is attached to the harness.

O is the slot or mortise, which is made tapering, and through which the spring d isrintroduced and lirmly held in its position by means ofa lug, c', (shown in red lines, Fig. 2,) which, after the spring is introduced and brought to its proper place, said lug Vis bent down over the end of the spring.

E is a thumb-lever, made with a groove of sufficient capacity to receive the spring d.

h is the joint Where the end of the thumblever meets the end of the main part ot the snap-hook. f

In constructing my improved snap-hook I usually make the mortise tapering, so that the spring cl will t closely and not draw through, and `vvheu the lug c is turned or bent down the spring is held' firmly in its place.

In constructing my snap-hook I do not confine myselt' to the particular form as above described for the spring, as shown in Fig. 3, as it may be made with 'alip turned upon the under side ot' the spring, as seen in Fig. 4, to lit a corresponding socket or mortise iu the body of the loop, and the lug used in the same manner as with the spring in t'oruu of Fig. 3. When the snap is completein all its parts the lthumb-lever may bc bentdown, as seen in red lines in Fig. 2, and when released will, by the force of the spring, resume its former position.

I do not claim, broadly', the use of a spring in haruesssnaps, as I am aware they have been heretofore used.

Having thus described my invention, what I do claim as new, and desire to secure by Let-4 ters Patent, is

The tapering spring d, fitting and working in a corresponding groove in the thumb-piece E, and passing through and secured by the mortiseO and luge', substantially as described.
